Dragon Ball series creator Akira Toriyama posted a comment in the Dragon Ball 30th Anniversary Super History Book about a certain live-action film and a new anime.

In the book, Toriyama stated:

Inside me, Dragon Ball became a thing of the past, but later I got upset at the live-action film, revised the script for the anime film, and complained about the quality of the TV anime. I guess at some point it became a work that I like so much that I can't leave it alone.

Fans speculated that Toriyama is talking about Dragonball: Evolution for the live-action part and Dragon Ball Super for the TV anime part. DB Super has suffered some animation errors, which were later fixed in the anime's home video release.

Aside from that comment, the book also includes a look back at the franchise's long history, comments coming from those involved in the series, and art from other manga artists paying tribute to one of Japan's most popular comic book series.
